Superb Sound and High-Power Performance Engineered Enclosures
Combining mechanical design expertise, new materials and a DuraFlex finish, MRX500 enclosures have been optimized for minimum weight and maximum ruggedness. Proven Networks Utilizing years of design experience, MRX networks are built using proven components in the most sophisticated topologies in their class. For maximum reliability, all input and loop-thru connections are made via Neutrik NL4MP connectors. In addition, the input connections can be easily reconfigured on the subs, for an efficient sub/sat cabling option. Taking a lead from the SRX700 Professional Loudspeaker System, these new components deliver extraordinary sound quality, power handling and performance yet, due to JBL’s advanced engineering, benefit from a significant weight savings over traditional designs. The result is a speaker system that will perform well beyond any other system in its class.

Differential Drive Transducers
JBL Professional designed a brand new range of 400W Differential Drive transducers in 12-inch and 15-inch configurations, perfectly matched to the brand new 1.5-inch annular polymer diaphragm compression driver producing a transducer engine that weighs significantly less than traditional transducer designs, yet their performance, sound quality and power handling are extraordinary.

Custom Waveguides
The constant beamwidth and power response of MRX500’s custom designed waveguide is perfectly matched to its direct radiating woofers which ensures superb coverage throughout the frequency range of the system.

Lighter. Louder. Legendary.

Dual Angle Pole Mount
The dual angle pole mount on the MRX512M and MRX515 offers much more control than the typical single mount. With a 10º down angle the speaker can be directed down toward your audience, keeping the energy off the back wall enhancing coverage and clarity.
